What Do Romantic Aliens See at the End of Their Alien Days?

When it comes to exoplanets, reality is catching up with science
fiction. Take Kepler-16b, a Saturn-size planet roughly 200 light-years
from Earth that circles not just one star but a pair of stars. Nicknamed
Tatooine, after the fictional home planet of Luke and Anakin Skywalker, this world must see sunsets that are twice as breathtaking.

Every
evening the two suns, which are never far apart in the sky, will set
one after the other in a dazzling display. Although it’s easy to picture
two hazy red stars dipping below the horizon, astronomers remain unsure
if these stars do in fact appear red. And on other exoplanets, “some of
these sunsets would actually not look exactly like they do on Earth,”
says Paul Anthony Wilson, an astronomer at the Paris Institute of
Astrophysics. “They would be quite different in color.”
